Kushandiswa kweSodium Cyanide Replacement Technologies muMigodhi midiki

ziviso

Muindasitiri yemigodhi, kunyanya yeMigodhi Midiki , kuburitswa kwesimbi dzinokosha dzakadai segoridhe nesirivha kwagara kuchishandiswa Sodium Cyanide . Zvisinei, kushandiswa kwesodium cyanide kunouya nezvinetso zvikuru zvezvakatipoteredza uye kuchengetedzeka. Ine chepfu yakawanda uye inogona kukonzera kusvibiswa kwakanyanya kumasosi emvura uye kukuvadza zvipenyu zvemumvura. Nekuwedzera kwekusimbiswa kwekuchengetedzwa kwezvakatipoteredza uye mitemo yakaoma pasi rose, migodhi midiki iri pasi pekumanikidzwa kukuru kwekutsvaga dzimwe nzira dzekubvisa simbi. Chinyorwa chino chinoongorora kushandiswa kweSodium cyanide Replacement Technologie mumigodhi midiki, nechinangwa chekupa kunzwisisa kwakazara kwemhinduro idzi dzinogara kwenguva refu.

Zvakaipa zveSodium Cyanide muMigodhi midiki

Njodzi dzezvakatipoteredza

Migodhi midiki inowanzoshaya nzira dzepamusoro dzekugadzirisa marara. Kana sodium cyanide ikashandiswa, pane njodzi huru yekuti cyanide ibude mumvura dziri pedyo panguva yekuburitsa. Kunyangwe huwandu hushoma hwecyanide hunogona kukuvadza zvakanyanya nharaunda. Semuenzaniso, inogona kutungamira kurufu rwehove nezvimwe zvipenyu zvemumvura, zvichikanganisa cheni yese yezvekudya zvemumvura. Pamusoro pezvo, cyanide inogona kuramba iri munharaunda kwenguva yakareba, zvichikonzera kukuvara kwenguva refu kuhunhu hwevhu nemvura.

Njodzi Dziviriro

Kubata sodium cyanide kunoda matanho akasimba ekuchengetedza. Migodhi midiki inogona kusagara iine zviwanikwa zvekuisa mari mumidziyo yakakodzera yekuchengetedza uye kudzidziswa kwevashandi vavo. Kusangana netsaona kune sodium cyanide kunogona kukonzera matambudziko akakomba ehutano kuvacheri, kusanganisira kutadza kufema uye kunyange kufa. Uyezve, kana pakaitika njodzi dzinongoitika dzoga kana tsaona, kuchengetwa uye kutakura kwe sodium cyanide mumigodhi midiki kunogona kuunza njodzi huru kunharaunda dzakapoteredza.

Alternative Technologies kune Sodium Cyanide

Thiosulfate Leaching

Thiosulfate leaching isiri-chepfu imwe nzira kune cyanide - based extraction. Inoshandisa thiosulfate ions kunyungudutsa goridhe kubva mu ores. Iyi nzira ine hushamwari hwezvakatipoteredza sezvo isingabudisi zvinhu zvine chepfu zvakanyanya. Mumigodhi midiki, thiosulfate leaching inogona kuve sarudzo yakakodzera sezvo inogona kuiswa kune akasiyana marudzi e ore. Zvisinei, ine mamwe matambudziko. Zvinogona kuda yekuwedzera maitiro optimization, sekudzora pH uye tembiricha yemhinduro yeleaching zvakanyanya. Zvakare, mari yekushanda yakakwira zvakanyanya kana ichienzaniswa necyanide leaching, zvakanyanya nekuda kwemutengo wetiosulfate reagents uye kudiwa kwemidziyo yakaoma mune dzimwe nguva.

Chloride Leaching

Chloride leaching inosanganisira kushandisa chloride ion kunyungudutsa goridhe nemamwe masimbi kubva mu ores. Inopa njodzi dzakaderera dzezvakatipoteredza zvichienzaniswa necyanide. Migodhi midiki inogona kubatsirwa nenzira iyi sezvo ichikwanisa kuenderana nemamiriro enzvimbo. Semuenzaniso, munzvimbo dzinowanikwa chloride-ine zvinhu zviri nyore, mutengo wemaagents unogona kudzikiswa. Nekudaro, kubata ne-zvigadzirwa uye marara kubva kune chloride leaching inogona kuve yakaoma. Chloride - marara akapfuma angada kurapwa kwakakosha kudzivirira kuora kwemidziyo uye kusvibiswa kwezvakatipoteredza.

Bioleaching

Bioleaching inoshandisa microbial chiitiko kubvisa simbi kubva ores. Iyi ndiyo yakagadzikana uye eco-hushamwari imwe nzira. Zvipembenene, zvakadai sehumwe utachiona, zvinogona kupaza simbi yacho ndokubudisa simbi dzacho. Kune migodhi midiki, bioleaching ine mukana wekuve nyore kumisikidza mune zvimwe zviitiko. Hazvidi midziyo yakanyanyisa. Nekudaro, kugona kwebioleaching kunogona kudzikiswa nezvinhu zvakaita serudzi rweore uye basa rema microorganisms. Mamwe maore anogona kusaora nyore nyore neanowanikwa tupukanana, uye kukura uye kuita kwema microorganisms kunogona kukanganiswa nemamiriro ekunze senge tembiricha uye pH.

Kushandiswa Kwenzvimbo - hushamwari Gold Dressing Agents

Kune mishonga yakawanda yegoridhe inochengetedza nharaunda inogona kutsiva sodium cyanide. Semuenzaniso, mushonga wegoridhe unochengetedza nharaunda we "Jinchán" wakagadzirwa neGuangxi Senhe High - tech Co., Ltd. une zvakanakira zve "chepfu shoma", "recovery rate" yakawanda, uye nyore kushanda. Mishonga iyi inogona kushandiswa mumaitiro akafanana nesodium cyanide, akadai se "heap leaching", "pool leaching", uye " Carbon - in - pulp processes". Inogona kubvisa goridhe kubva mumhando dzakasiyana dzeore, kusanganisira dzine makemikari akaomarara. Mumwe muenzaniso ndeweCNFREE sodium cyanide substitute, iyo inogona kushandiswa zvakananga pakushongedza nekuchenesa goridhe pasina kuchinja michina yekutanga uye maitiro ekugadzira cyanide, zvichizadzisa chinangwa chekuchengetedza nharaunda yakasvibirira.

Matambudziko uye Mhinduro muKushandisa Alternative Technologies muMigodhi Midiki

Mutengo - kubudirira

Rimwe rematambudziko makuru emigodhi midiki pakutora mamwe matekinoroji mutengo - kushanda zvakanaka. Dzakawanda dzimwe nzira, senge thiosulfate leaching, inogona kunge iine yakakwira yekutanga mari yekudyara yemidziyo uye reagents. Kugadzirisa izvi, zvimbambaira zvidiki zvinogona kufunga kushandirapamwe nemasangano ekutsvagisa kana makambani makuru emigodhi kuti vagovane mutengo wekutsvaga nekugadzira nzira dzinodhura - dzinoshanda. Pamusoro pezvo, rubatsiro rwehurumende kana kurudziro zvinogona kupihwa kukurudzira zvimbambaira kuti zvishandise matekinoroji aya.

Unyanzvi hwehunyanzvi

Migodhi midiki inogona kushaya hunyanzvi hwehunyanzvi hunodiwa kuti ushande nekugadzirisa mamwe matekinoroji aya. Zvirongwa zvekudzidzisa zvinogona kurongwa nemasangano emaindasitiri kana masangano ehurumende kuti vadzidzise vashandi vemumigodhi mashandisirwo akanaka enzira itsva dzekuchera. Semuenzaniso, kudzidziswa nezve maitiro ekudzora ma paramita mu thiosulfate leaching kana maitiro ekugadzirisa hutachiona nharaunda mu bioleaching. Uyezve, vanopa tekinoroji vanogona kupa - saiti tekinoroji rutsigiro kumigodhi midiki panguva dzekutanga nhanho dzekutora matekinoroji matsva.

Regulatory Adaptation

Mamiriro ekugadzirisa zvicherwa ari kuramba achichinja. Migodhi midiki inofanirwa kuona kuti mamwe matekinoroji avanotambira anoenderana nemitemo yemuno neyekunze. Izvi zvinoda kurukurirano yepedyo nevane masimba. Masangano anodzora anogonawo kuita basa nekupa nhungamiro dzakajeka pamusoro pematanho anogamuchirika ekukanganisa kwezvakatipoteredza uye mwero wekuchengetedza kune mamwe matekinoroji, zvichiita kuti zvive nyore kumigodhi midiki kugadzirisana.

mhedziso

Kushandiswa kwesodium cyanide kutsiva tekinoroji mumigodhi midiki kwakakosha mubudiriro inoenderera muindasitiri yezvicherwa. Kunyangwe paine zvimhingamipinyi zvakaita semutengo - kushanda zvakanaka, hunyanzvi hwehunyanzvi, uye kuchinjika kwemitemo, mabhenefiti eaya mamwe matekinoroji maererano nekuchengetedza kwezvakatipoteredza nekuchengetedza akakosha. Nekugadzirisa zvimhingamipinyi izvi kuburikidza nekushandira pamwe, kudzidziswa, uye kutaurirana zviri nani nevane masimba, zvimbambaira zvidiki zvinokwanisa kuchinjika kuenda kukushandisa nzira dzakasimba dzekuchera, kuve nechokwadi chekushanda kwenguva refu kwekushanda kwavo uku ichideredza kukanganisa kwayo kune zvakatipoteredza uye nzanga.
